Press <Esc> to quit (or toggle) the explorer window

[winkee01]

I am trying to bind the key <Esc> to quit the neo-tree explorer window, however it does not have any effect, why?

opts = {
  filesystem = {
    window = {
      mappings = {
        ["Esc"] = "close_window",
        ["l"] = "open",
        ...
      },
    },
  }
}

Can someone help me to achieve that? Thanks a lot!

I have tried this, no effect as well:

opts = {
  filesystem = {
    window = {
      mappings = {
        ["Esc"] = function(state)
          require("neo-tree.command").execute({ action = "close" })
        end,
        ["l"] = "open",
        ...
      },
    },
  }
}

use <Esc>, not Esc

Esc translates to the literal sequence E s c
